On my route I use three different track rules with no apparent problem. 1 for the interurban track, one for the 'yellow dirty' and 'bridge' track (GN Mainline trackrule), and one for short segments of 'rail only' track for ashpits (ATSF track rule).
Yes, the appearance of different types of track within a track rule can be and often are different from similar track types in other track rules. In the example I gave above, the 'rail only' track from the ATSF track rule is clearly a different rail size from that of the GNMainline track rule, but all are standard gauge.
